Answer:
Hey buddy don't worry this lesson is about aquatic equations and solving quadratic questions in a graphical manner. Quadratic questions have 2 equal or different solutions and the largest power or exponent of X is 2 or squared. If you need more help please let me know
Answer:
I would stay direct vartation
Step-by-step explanation:
For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
Answer:
m = -21
Step-by-step explanation:
9+m/3=2
1. Subtract 9 from both sides
9 - 9 + m/3 = 2 - 9
m/3 = -7
2. Multiply both sides by 3
3 (m/3) = -7 (3)
m = -21
why don't you just search it up instead of doing it here when it takes time for someone to answer the question
Answer:
y=1; x=2
Step-by-step explanation:
Substitution:
x=2y
2x+5y=9
=> if x=2y, plug in the x value into other equation, so
----------------------------------------------------------------------------
2(2y)+5y=9
4y+5y=9
9y=9
y=1
You have the Y value, so now solve for X
-----------------------------------------------------------------------
plug in y value to x=2y
so x=2(1)
x=2
